Display device for vehicle

A display device for a vehicle, which reflects a display image to be displayed on a display, on an optical system, projects the display image on a wind shield of the vehicle, and allows a virtual image corresponding to the display image projected onto the wind shield, to be viewed by a driver from a viewpoint position of the driver of the vehicle, the display device comprising:

• a detection unit that detects an actual viewpoint position of the driver;
• and
• a controller that prepares the display image on a basis of an original display image, wherein
• the controller displays an image at a time of seeing a three-dimensional object for distortion correction formed in a virtual space, from a reference viewpoint position of the driver, on the display, as the display image,
• the controller includes
• an acquisition unit that acquires the original display image,
• a texture mapping unit that performs texture mapping by pasting the original display image to the three-dimensional object for distortion correction, in the virtual space, and
• an adjustment unit that adjusts the three-dimensional object for distortion correction, according to a positional change between the reference viewpoint position and the actual viewpoint position, in the virtual space,
• the three-dimensional object for distortion correction is a curved surface model which is reversely distorted to offset a distortion occurring in the virtual image with respect to the display image, due to at least one of the wind shield and the optical system, and
• the adjustment unit changes a position of the three-dimensional object for distortion correction from a reference position, according to the positional change.
